 flexed, with two small black median spots, a median line and slight trans- 

 verse strige ; breadth between the eyes a little smaller than the eyes toge- 

 ther : face transversely striated, stronger and more oblique on the sides : 

 frons longer than broad, flat at the base, more convex at the tip, the 

 grooves and base of a brighter citron yellow : genae with parallel circu- 

 lar streaks on the npper border which is circular, slightly sinuate be- 

 neath the eyes, the portion below the eyes and antennae, glossy : cly-

 rounded at the tip and armed on the disc and sides with a few spiny 

 hairs. 



? last ventral segment a little longer on the sides than the penulti-
